The revolution of earth around the sun and the tilt of earth’s axis cause the changing of seasons. TRUE
<u>Explanation:</u>
Earth is slightly tilted at its axis. This causes a change in the amount of sunlight reaching each hemisphere. Due to the tilt one hemisphere will be closer to the sun while the other will be at a greater distance. When the earth revolves around the sun , the hemisphere that is closer to the sun changes.
The hemisphere closer to the sun will experience summer and the hemisphere away from the sun will experience winter.
Answer:

Agua: Pure substance
Agua de limón: Homogeneous mixture
Refresco con gas: Heterogeneous mixture
Arroz: pure substance
Frijoles: pure substance
Frijoles con caldo: heterogeneous mixture
